4. (6 pts) For the diatomic molecule F2 : (a) Give the Lewis structure and use valence bond theory to predict the number and type of bonds (,, etc.) and the number and type of non-bonding/lone pairs. (b) Use molecular orbital theory to describe the bonding in F2 including the bond order. Give the number and type of bonds (,, etc.) and the number and type of non-bonding /lone pairs. (Note: non-bonding / lone pairs of electrons are electrons that are not involved in bonding of any type). (c) Compare your answers to (a) and (b). How are the two descriptions similar? Different
